T 0 all whom it may concern:

Be it known that I, NATHAN W. PER- KIXB, Jr., a. citizen of the UnitedStates, residing at East Orange, county of Essex, and State of New Jersehave invented certain new and useful improvements in Paper-Roll Holders,of which the following is a specification.

This invention relates to paper roll holders.

The present invention has for its object the provision of a paperrollholder for adding and listing machines and, more particularly, forcombined adding and typewriting machines having novel means whereby itmay be shifted into position for the use of the paper on the platen ofthe machine when it IS desired to list or add separately from the usualoperations on the peaper carried-by the laten and which may readily andquick y swung out of position when it is not desired to use the paperfrom the roll.

A- further object is the provision of a pa er roll holder which mayber'eadily attac ed to anycombined adding and typewritingmachine, or thelike, having novel means whereby it is locked when in operative positionso that a' roper degree of rigidity to secure a suitab e positioning andguiding of the paperis maintained when the aper from the roll is' beingused and whic vma be swung aside and automatically unlocked by simplemanipulation when the'paper from the roll is not desired.

A still further object of the invention is the revision, in a device ofthe character set orth, of novel means for locking the carriage of themachine so that it cannot shif while the pug pr from the roll holder isteing used on t e platen in an adding operation, or the like, suchlockin of the carriage being automatically effects on p0- si'cioning thepaper roll holder for use of the paper from the roll thereof.

In the present invention there-is provided a self-contained roll holderand movable parts, all adapted for attachment to an adding andtypewriting machine wherein the positioning of the device for-use of thepaper from the roll thereof causes locking so that it will be maintainedin position, and raising the paper holding part of the attachment willcause automatic unlocking orrelease of the roll holder, thus requiringno attention on the part of the operator other than positioning thedevice when the paper of the roll thereof is to be used and swinging itaside when its use is not further required.

Having the foregoing objects, and others not specifically mentioned, inview, the invention embodies certain features of construction set forthmore fully hereinafter and recited in the appended claims.

In the 'accompanying drawings :--Figure 1 is a pers ective of a part ofa combined adding and typcwriting machine with the invention applledthereto in position for use; Fig. 2, a similar view with the roll holderdropped downwardly; Fig. 3, a detail side elevation, partly in section,show ing the roll holder in position for use; Fig. 4, a detail rearelevation of a portion of the roll holder when in the position shown inFi 3;'Fig. 5,-a detail plan of the carriageloc ing device, a portion ofthe rack hein shown; and Fig. 6, a detail erspective o i the jointbetween the main rame and the pa er-holding frame, the parts beingdetacied and showing the position one of the latching arms assumes whenthe device is inthe osition shown in Fig. 3.

In t e drawings so much of a combined typewriter and adding machine ortypewriter with adding attachment is shown as will give a clearunderstanding of the cooperation of the invention therewith, it beingunderstood that the present invention is attached to the rear part ofthe frame of the machine.

The rotary platen is shown at S, being mounted in a suitable carriage totravel transversely of the machine and having a rack Cf". The usualpapef'table appears at S.

Mounted on the frame of the machine is a guide 47 in which slides alatch B" having a suitable heel B A spring B inter osed between the heeland the gpide 47 an suitably sustained against buc ling by ins 29afiords means for normally retr cting the tooth of the latch B out ofengagement with the rack C.

54 designates a bracket which is suitably secured to the frame of themachine by screws or other fastenings and is provided with u -turnedears having notches 54*. The rol carrier has two arms 55 which arepivoted to the cars by screw pivots l4 and are provided with shoulders55" ads ted to strike the hastv of the bracket when t e roll latches 58which are of bell-crank construc-' by a spindle 2 having a head 13 atone end and a-screw tip at the other end, the spindle assing looselythrough the hub of one of t e arms 55 and the tip'screwing into the hubof the other arm 55.' The paper roll is loosely mounted on the spindle 2and the latter is removable from the arms 55 to permit the paper roll tobe put on or taken ofi.

Pirated on the hubs of the arms 55 through which passes spindle 2} arethe tion, the lower legs being provided with lugs 58 adapted to engagethe notches 54c when the device is in its raised osition and thereforelock the entire device in that position, the latches being given atendency to engage the notches 54" by the s rings 80 which are connectedto said late es' and to .thc arms 55. The other angles of the arms 55are connected and braced by a rod 3,

screws l5 entering the ends thereof.

Swingingly mounted on the rod 3 are the arms 0 the paper guide 57, thesearms being provided with hubs each having a flat 15"). The aperguide hasa crosspiece 57 over win platen S, and said cross-piece is provided withcushions 91 adapted to sup 'ort' it on thus prevent spratching of the par table; Thepapen guide also has a paper ife 90 extending thereacross atits end and connected thereto by screwslfi. The end-of the paper-strip,after passing"around the platen S, passes up between the arms 57*rasped and drawnso that upon being toward" the operator, it will bebrought against the knife and readily sevened.

The lower end of each of the arms 55 has a cam 55* one of-which ispositioned to ongagc the heel B 'and press the latch B into engagementwith the rack C of'the carriage of the machine when the device is in itsraised or operative position, and to swing out of the way and releasesaidlatch to permit the spring 29" to throw the latch out of engagementwith the rack C" when as shown in Fig. 1.

the paper roll holder is thrown down, as shown in Fig. 2. The members 55strike 54" when the roll holder is in raised position,

'iiuarms 58"" of tho latches 58 are adapted to rest upon the hubs 85" atall limos, being drawn against said hubs b the swings 80". Win-n thepaper gui o is t ilO\\'|i down to opol'ntive position, as shown .platenS,

ioh the paper from the roll-passes prior to being passed. around theown, and

mosses in 1 and 3, the flats 15* are then under the tips of' the arms58* so that the lugs 58* are then thrown into the notches 54* by thesprings 80* and, consequently, the

entire paper roll holder is locked in operative position. As soon,however, as the erguide 57 is raised, the rounded or a gyindrical partsof the hubs 35 comes unerneath the arms 5583 and raise them, thusreleasin, the lugs 58 from the notches'o l and ena ling the entiredevice to be thrown .backwardly to lowered position, in doing which thecam 55" releases the latch B from the rack C; v

When not desired for use, the attachment lies in the osition shown inFig. 2. When it is desire to lock the carriage and to add or listnumbers on the strip from the paper roll, the entire attachment is drawnup- ,wardly andthe pa er guide brought down upon the aper ta le S,whereupon the paper kni e 9Q- lies immediately over the and the paper isthen threaded across the su port 57* and around the platen'S an upwardlyunder the knife 90 When the items have been printed on the strip, thestri is detached by drawing it against thc'ltni e, and'on lifting thearms '57., the latches 58 a're'released from the notches 54K, whereuponthe entire device may be dropped to the rear-of the machine. When theattachment is raised to bring it to the position shown in'Figs. i and 8,the cam 55*, b ressin against the heel 13" causes t e atoh to en age therack C of the carriage of the ma inc and lock the carriage and platenagainst movement.
